thread

thread: [OE] A thread is etymologically something ‘twisted’. The word comes from a prehistoric Germanic *thrǣthuz, which was derived from the base *thrǣ- ‘twist’ (source also of English throw). Other descendants of *thrǣthuz include Dutch draad, Swedish tråd, and Danish traad ‘thread’ and German draht ‘wire’.
=> throw

thread (n.)

Old English þræd "fine cord, especially when twisted" (related to þrawan "to twist"), from Proto-Germanic *thredu- "twisted yarn" (cognates: Old Saxon thrad, Old Frisian thred, Middle Dutch draet, Dutch draad, Old High German drat, German Draht, Old Norse þraðr), literally "twisted," from suffixed form of PIE root *tere- (1) "to rub, rub by turning, turn" (see throw (v.)). Meaning "spiral ridge of a screw" is from 1670s. Threads, slang for "clothes" is 1926, American English.

The silk line, as spun by the worm, is about the 5000th part of an inch thick; but a spider's line is perhaps six times finer, or only the 30,000th part of an inch in diameter, insomuch, that a single pound of this attenuated substance might be sufficient to encompass our globe. [John Leslie, "Elements of Natural Philosophy," Edinburgh, 1823]

thread (v.)

"to put thread through a needle," mid-14c., from thread (n.); in reference to film cameras from 1913. The dancing move called thread the needle is attested from 1844. Related: Threaded; threading.
